KIDS TRIVIA

Detailed explanation-1: -During photosynthesis, the photolysis of water releases the oxygen present in the environment. The amount of oxygen present in the environment is released massively by plants. Hence if we cut down the trees the amount of oxygen present in the environment will decrease.

Detailed explanation-2: -Thus, trees maintain the necessary level of oxygen in the environment and improve the quality of air for all life that is dependent on oxygen. When trees are cut, the amount of oxygen decreases. Thus (A) is the correct option.

Detailed explanation-3: -Trees absorb and store carbon dioxide. If forests are cleared, or even disturbed, they release carbon dioxide and other greenhouse gases. Forest loss and damage is the cause of around 10% of global warming.

Detailed explanation-4: -Plants take up carbon dioxide exhaled by animals and release oxygen inhaled by animals. Thus, forests maintain a balance between the two gases in atmosphere. Deforestation disturbs this balance and increases the amount of carbon dioxide in atmosphere.
